Annotation
See example for LPFNIG_ART_TEXTOVERFLOWNOTIFYFUNC callback function.
If the text needs less space then the total mark bounds some of the marks may be empty. The function does not change the mark bounds and does not repaint them.
The function can be applied only for Typed Text(ART_MARK_TYPED_TEXT) and Attach-a-Note(ART_MARK_ATTACH_A_NOTE) marks. If the lpMarkIndexes array contains indexes of marks different from ART_MARK_TYPED_TEXT or ART_MARK_ATTACH_A_NOTE an error will occur, and the function will do nothing.
